Product details
Overview
The MAX16000ATC+ from Maxim Integrated is a low-voltage, quad-voltage microprocessor supervisor IC in a 12-pin TQFN (4mm × 4mm) package, monitoring four independent supply rails (e.g., 3.3V, 2.5V, 1.8V, and adjustable down to 0.4V) with ±5% or ±10% threshold tolerance selection, 140ms minimum reset timeout, and open-drain outputs with internal 30µA pullups - used for power sequencing and fault detection in multivoltage ASIC systems.
For engineers reviewing the MAX16000ATC+ datasheet, MAX16000ATC+ pinout, MAX16000ATC+ application, or MAX16000ATC+ equivalent, this device delivers deterministic reset assertion on any monitored rail undervoltage, manual reset input support, margin enable for production testing, and guaranteed logic-state integrity down to VCC = 1V - critical for high-reliability industrial and telecom power management.
Technical Context
The MAX16000ATC+ implements independent voltage monitoring per input (IN1–IN4), each with user-selectable 5% or 10% threshold tolerance via the TOL pin, and asserts dedicated open-drain outputs (OUT1–OUT4) without external pullups. It lacks a watchdog timer or shared RESET output - distinguishing it from MAX16001/MAX16002 variants.
Its reset timeout is fixed at ≥140ms (internally set by SRT = VCC), and all outputs remain asserted until their respective input voltages exceed thresholds with hysteresis of 0.5% VTH. The device operates across –40°C to +125°C and draws only 45–65µA supply current at VCC = 3.3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Monitored Voltages | Four independent rails (IN1–IN4), configurable via part variant (e.g., MAX16000A: 3.3V/2.5V/ADJ/1.8V) |
| Threshold Accuracy | ±5% (TOL = GND) or ±10% (TOL = VCC); adjustable down to 0.366V–0.400V |
| Reset Timeout | ≥140ms minimum (fixed internal setting; SRT tied to VCC) |
| Supply Voltage Range | 1.0V to 5.5V; guaranteed correct logic state down to VCC = 1V |
| Supply Current | 45µA (min) to 65µA (max) at VCC = 3.3V, TA = +25°C |
| Output Type | Open-drain OUT1–OUT4 with internal 30µA pullup to VCC; no external resistors needed |
| Operating Temperature | –40°C to +125°C ambient; qualified for automotive-grade thermal stress |
Pinout & Package
MAX16000ATC+ uses a 12-pin TQFN package (4mm × 4mm, exposed pad), pin-compatible with other MAX16000-series variants in the same outline (21-0139). The exposed pad (EP) is internally connected to GND and must be soldered to the PCB ground plane for thermal performance.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN3 | Third monitored input voltage (e.g., 1.8V or adjustable); threshold set by part variant and TOL pin |
| 2 | IN4 | Fourth monitored input voltage (e.g., adjustable or 1.8V); supports down-to-0.4V detection |
| 3 | GND | Ground reference for all analog and digital circuitry; connects to EP |
| 4 | VCC | Unmonitored bias supply (1.0V–5.5V); requires 0.1µF bypass capacitor to GND |
| 5 | OUT3 | Open-drain output asserting low when IN3 falls below threshold; 30µA internal pullup |
| 6 | OUT4 | Open-drain output asserting low when IN4 falls below threshold; 30µA internal pullup |
| 7 | MARGIN | Active-low input to deassert all outputs during margin testing (forces high-Z state) |
| 8 | OUT2 | Open-drain output asserting low when IN2 falls below threshold; 30µA internal pullup |
| 9 | OUT1 | Open-drain output asserting low when IN1 falls below threshold; 30µA internal pullup |
| 10 | IN1 | First monitored input voltage (e.g., 3.3V or adjustable); primary rail supervision point |
| 11 | IN2 | Second monitored input voltage (e.g., 2.5V or adjustable); supports multivoltage sequencing |
| 12 | TOL | Threshold tolerance select: GND = ±5%, VCC = ±10%; sets hysteresis and accuracy band |
Key Features
| Feature | Design Value |
|---|---|
| Independent per-rail monitoring | Four dedicated outputs (OUT1–OUT4) allow discrete fault isolation and targeted system response |
| Adjustable low-voltage thresholds | Configurable down to 0.366V (TOL = VCC), enabling supervision of sub-1V core rails |
| No external pullup resistors required | 30µA internal pullups eliminate BOM count and layout area for open-drain outputs |
| Guaranteed operation at low VCC | Correct logic state maintained down to VCC = 1.0V - supports brownout-safe boot sequences |
| Production test support | MARGIN pin enables full output deassertion during voltage margining without affecting supervision logic |
Applications
| ASIC Power Sequencing | Industrial Control Unit |
|---|---|

IC Role / Device Role / Timing Role: Fault-detection node that asserts individual outputs to isolate failed subsystems without global reset. Use Value: Enables partial system recovery - e.g., maintaining communication while disabling faulty analog front-end. |
| Telecom Line Card | Storage Controller Board |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX16001ATC+ | Includes shared active-low RESET output and watchdog timer (1.6s timeout); same pinout and package | Required where system-level reset coordination or software watchdog supervision is needed | Select MAX16001ATC+ if centralized reset assertion or WDI-based firmware health monitoring is required |
| TPS3307-33D | Triple-supervisor (not quad); fixed 3.3V/3.3V/3.3V thresholds; no adjustable inputs or MARGIN function | Limited to identical-rail redundancy; lacks per-rail independence and test support features | Choose TPS3307-33D only for cost-sensitive dual- or triple-rail applications without margining needs |
Compared with MAX16001ATC+, the MAX16000ATC+ trades watchdog capability and shared RESET for pure per-rail autonomy and simplified test integration; versus TPS3307-33D, it offers true multivoltage flexibility and production-ready margin enable - making it optimal for complex ASIC power domains.

FAQ
What is the function of the TOL pin on the MAX16000ATC+?
The TOL pin on the MAX16000ATC+ selects threshold tolerance: connecting it to GND configures ±5% accuracy for each monitored input, while tying it to VCC selects ±10% tolerance. This directly affects hysteresis (0.5% VTH) and determines how tightly the device enforces voltage limits during power-up and brownout conditions.
Does the MAX16000ATC+ include a watchdog timer?
No, the MAX16000ATC+ does not include a watchdog timer. Watchdog functionality is present only in MAX16001/MAX16002/MAX16004–MAX16007 variants. The MAX16000ATC+ is strictly a quad-voltage supervisor with independent outputs and no WDI or WDO pins.
Can the MAX16000ATC+ monitor voltages below 1.0V?
Yes - the MAX16000ATC+ supports adjustable thresholds down to 0.366V (at TOL = VCC) and 0.388V (at TOL = GND), enabling supervision of sub-1V core rails such as 0.9V or 0.8V domains common in advanced ASICs and low-power processors.
What is the purpose of the MARGIN pin on the MAX16000ATC+?
The MARGIN pin on the MAX16000ATC+ is an active-low input that forces all four outputs (OUT1–OUT4) into a high-impedance (deasserted) state when pulled low - allowing safe voltage margin testing without triggering false resets or disrupting system operation.
Is the MAX16000ATC+ pin-compatible with other MAX16000-series variants in the same package?
Yes - the MAX16000ATC+ shares the identical 12-pin TQFN footprint (outline 21-0139) and pin mapping with all MAX16000x variants in the T1244+4 package, including MAX16000BTC+, MAX16000CTC+, etc.; only the internal threshold configuration differs per part number.
